12 Claims.

My invention relates to supports for conductors and has particular reference to supporting trolley conductors.

One of the objects of my invention is to provide a hanger in which the parts are relatively adjustable in order that the hanger may be applied to span wires which are obliquely disposed to the horizontal or may be applied to other supports the axes of which are obliquely disposed to the vertical and in all cases the trolley wire and its ear or clamp may be positioned normal.

Other objects will be disclosed as I further describe my invention.

My invention resides in the new and novel construction, combination and relation of the various parts hereinafter described and as shown in the accompanying drawing:

In the drawing:-

Fig. 1 is a side view in elevation and partial section of my invention.

Fig. 2 is a side view of my hanger as taken at 90 from that of Fig. 1.

Fig. 3 is a top view of my hanger.

Fig. 4 is the top view of the suspension yoke.

Fig. 5 is a top view of the suspending stud.

Fig. 6 is a side view of the top portion of the hanger body showing the socket formation.

Fig. 7 is a sectional view on the line 77 of Fig. 3.

In the preferred embodiment of my invention I employ a hanger body 1 provided with a downwardly projecting flange to form an inverted cupshaped receptacle and positioned within the receptacle is a second flange 2 also forming an inverted cup-shaped receptable in which is mounted the supporting stud 3 having a conically-shaped head 4 and projecting threaded portion 5. The

lower edge of the flange 2 is turned inwardly to provide an annular flange 6 to better aid in the support of the stud 4.

The receptacle formed by the downwardly projecting flange of the'body 1 and the flange 2 are each filled with insulating composition 7 which is molded in position under pressure and maintains the body 1 and the stud 3 in separated insulated relation.

The body 1 is provided with a'dome-shaped portion 8 which has an inverted T-shaped side opening 9 opening into a receptacle 10 and also having a top opening 11. The side opening 9 is of less extent than the receptacle 10 and the inner upper surface 12 of the receptacle 10 is curved to provide a bearing for-the suspension stud 13.

The stud 13 is provided with a head portion 14 and a threaded shank 15. The head 10 has a curved surface 18 corresponding to the curvature of the surface 12. The stud 13 projects through the slot 11 which is sufliciently large to permit of limited universal movement of the stud 13 relative to the body 1 during which movement the curved surfaces 12 and 16 move in contact and relative to each other. The outer surface 17 of the dome 8 is curved and has a center of curvature common with that of the inner surface 12 of the dome.

Mounted upon the exterior of the dome 8 is a suspension yoke 18 having projecting arms 19 and the ends thereof formed with slots 20 to receive the cross span wire shown in dotted lines by which the device is supported. In Fig. 1 the axis AA of the span wire is shown horizontal which is the usual position which the span wire takes but there are occasions when the axis of the span wire at the point of supporting the hanger is obliquely disposed as shown by the line BB in Fig. 1 and in that case it is necessary to have the yoke member positioned with respect to the body 1 of the hanger such that it will grip the span wire and still maintain the axis C0 of the stud 3 vertical.

The yoke 18 is provided with an inverted cupshaped recess 21 having a spherical surface 22 corresponding to the surface 17 on the dome with which it contacts.

An opening 23 in the yoke connects with the recess 21 and has two flat surfaces 24 which are engaged by the flattened surfaces 25 on the stud 13 which extends through the opening 23 and pre-' ,vents relative rotation of the yoke and stud. The yoke and stud will have limited universal movement relative to the body. Mounted upon the end 15 of the stud 13 is a nut 26 and a spring lock washer 27 by means of which the yoke and body may be held in any adjusted position desired or the tension between the yoke and dome may be so adjusted that the yoke and body will move under stress thus constantly adjusting themselves to conditions.

The yoke is provided with a groove 28 to receive the span wire and thus the span wire is in engagement only with the yoke and does not contact with the body of the hanger.

Integrally formed with the body 1 is a projecting lug 29 which is engaged at times by the lug 30 integrally formed with the yoke 18. These lugs form convenient means for applying the body 1 to the conductor clamp or ear secured to the lower end of the stud 13 before the hanger is positioned upon the span wire.

In installing the hanger the nut 26 is loosened sufficiently to permit the yoke and body to be rotated relative to each other and the end 5 of the stud 3 is then brought into cooperative relation with the trolley wire ear or support and the yoke 18 is then rotated in a clockwise direction (see arrow, Fig. 3) until the lug 30 engages the lug 29 and continued rotation of the yoke 18 will rotate the body 1 and secure the stud 3 to the supporting ear or clamp. When this operation has been completed the yoke 18 is then rotated so as to be appled to the span wire and this having been done the nut 26 may be tightened to hold the parts in a fixed relation or the nut may be tightened sufficiently only to permit the parts to move under stress suflicient to overcome the friction between the yoke 18 and the dome 8.

If it is desired to replace the trolley wire clamp or ear with a new one then the yoke is disengaged from the span wire and rotated in a counterclockwise direction until the lug 30 engages the lug 29 on the opposite side to that shown in Fig. 3 and continued rotation will then disengage the stud 3 from the clamp or ear.

Modifications may be made to the disclosure herein shown and described as, for instance, the device may be made to attach to other forms of supports than a span wire and still have the axis of the support adjustable relative to the axis CC of the stud 3. c
